    [ZOOKEEPER-1818] Correctly handle potential inconsistent zxid/electionEpoch and peerEpoch
during leader election

    This is similar to the 3.4 implementation in Jira ZOOKEEPER-1817, main differences with
that:
    
    1. removed bcVote, in Vote.equals it will skip compare peerEpoch when one of the version
is 0x0.
    2. added detailed scenarios which we tried to solve with peerEpoch update and the change
in Vote.equals.
    3. removed ooePredicate with inlined one, since master code is tracking voteSet..
    4. improved the tests to make it cleaner.
